IMPROVEMENT IN JAGKS FOR BOOTS AND SHOES.

Specification forming part of Letters Patent No. 199,304, dated January15, 1878 application tiled December 13, 1877.

To all 'whom it may concern:

Be it known that I, GORDON MCKAY, of Cambridge, in the county ofMiddlesex and State of Massachusetts, have invented an Improved Jack forBoots and Shoes, ot' which the following is a specification:

This invention relates to a jack for holding boots and shoes while theyare being lasted, or the outer sole applied to be nailed or fastened.

The invention consists, primarily, in a system of gages adapted to thejack, to assist in placing the outer sole in correct position withreference to the upper and inner sole, to permit the proper applicationof the sole thereto.

Figure 1 represents, in top view, a jack oonstructed in accordance withthis invention; Fig. 2, an end elevation thereof; and Figs. 3 and 4 aredetails to be referred to.

. The parts below the top plate of the jack a are and may be of anyusual construction. The ring bis operated in the usual way to move theheel-pin c, and the toe-rest d is held in one of the sockets 2 of thetoe-rest holder e, all as now common.

In a certain class of shoes, described in United States Letters PatentNo. 189,834, the sole is filled with partially-driven tacks or headedfastenings, and placed in position on the inner sole of the shoe. Theheaded fast- A enings are then driven into the upper and inner sole, astherein described, by means of a hand-hammer.

To aid the operator in placing these soles partially lled with nails incorrect position upon the lasted upper and inner sole, I have providedgages h h1 h2 on rods f, preferably made adjustable, such gagesreceiving between them and bearing upon the edge of the outer sole,thereby determining its position with reference to the upper and innersole.

The gage-faces are in two planes, to fit, one portion, gl, against theupper g2, and the other, g, against the edge of the outer sole 5v. Therods f, extending down from the gages, are held in ears 3 4 ofadjustable holding arms or levers 5, pivoted at 6, such arms having eX-tensions 7, resting on upwardly-pressing springs fi, adjusting set-screwj in yokes 8 (see Fig. 4) working against the upper portions of 7. Thisset-screw j, or gage-adjusting device, determines the position of theface of the gage with reference to the center of the lasted shoe, andthe springt' permits the gage to be moved backward from such position.Each rod f is provided with a guide-block, 7c, to move over the part 5,and maintain the face of the gage at the proper angle with reference tothe shoe, and each rod is provided with a sprin g, Z, to hold it up. Theouter sole, studded with fastenings and placed between the gages, set toplace the sole in correct position, has the fastenings driven by ahammer, and as the outer sole approaches the inner sole the gages yield.

The gages h are for the side of the sole, the gage h1 for the toe of thesole, and the gages h2 for the heel of the sole.

I claim- I l. The combination, with a boot or shoe holding jack, ofgages to govern the position of the outer sole with reference to thelasted upper and inner sole, Substantially as described. n

2. The combination, with last holding and adjusting devices, of gages hfor the side edges of the outer sole, to operate Substantially asdescribed.

3. The combination, wit-h last-holding devices, of gages for the sideedges and toe of the outer sole, substantially as described.

4. In an apparatus to attach the outer sole to the upper and inner sole,a gage to bear against the edge of the outer sole, and against the upperbelow it, to operate substantially as described.

5. The outer-sole gages and their rods, in combination with a spring topermit themovement orn the rods and gages in the holdingarm.

6. The combination, with a last holding and adjusting jack, of gages forthe edge of the outer sole, and adjusting devices to control theposition of such gages as to their dis tance from a central line drawnlongitudinally through the last, Substantially as described.

In testimony whereof Ihave signed myname to this specification in thepresence of two subscribing witnesses.

GORDON MCKAY.
